Kisame did NOT laugh at them. Silly, silly man, they were MILES from the river. Just because the path was short, didn't mean the path was.
Wait, had he explained that?
He thought the had.
But maybe not clearly enough. Perhaps he really should invest in sock puppets and pop up books...
The path was a perfectly straight line in a curved world, that was the best explanation Kisame'd gotten when he'd tried to map it. Falling off the path mean, falling into the woods...
ARGH.
Fine. If they wandered off the path, he'd grab em. Morons.
